Weight Loss Medicines

Weight loss medicines used to control obesity via pharmacotheraphy in Malaysia such as Orlistat and Phentermine are available from hospitals or clinics.

Pharmacotheraphy is the treatment via prescription drugs or medicines. These are prescribed by your doctor. For weight loss in Malaysia, pharmacotheraphy is used by doctors in addition to diet and exercise regiments.

Weight loss medicines are prescribed after a thorough check up with the doctor and evaluation of current health risks such as diabetes and cardiovascular diseases . The recommendation in Malaysia is that weight loss medicines can only be prescribed if you have undergone a weight loss program that involved a diet and exercise routine earlier, over a certain period of time.

There are two major anti-obesity drugs used in Malaysia, namely Orlistat and Phentermine. Another weight loss medicine, Sibutramine (Reductil), was banned in 2010 due to health risk factors.

It should be noted that weight loss medicines or anti-obesity drugs are not magic pills that will give you sustainable weight loss. Diet and lifestyle modification are still very much required by your doctor to ensure that your weight loss will be achieved and can be sustainable. These weight loss drugs are also not meant for young children and the elderly. There is a risk also of developing tolerance to these medicines.
